Label Statements

This week I join the Peachpit Commons Blog with five ActionScript tips to help make your transition from ActionScript 2 to ActionScript 3 a little less painful.

First up, Label Staments.

videoPlayer, a reserved word?

I have been going crazy trying to determine why I could not add an FLVPlayback component to my AS2 application without creating an infinite loop. Apparently, I had a movie clip that contained the FLVPlayback I was attempting to add, which was named videoPlayer in the library. I'm happy I can rest now, but it leaves me wondering, is videoPlayer a reserved word?

FileReference to download server-side file

I was asked today how to download a server-side file through the FileReference object. The issue was that the server-side file was executing before downloading. The FileReference object uses http, rather than ftp, to download files, so any server-side script will execute before being downloaded. You either need to zip it and use the zip as a download or use an intermediate server-side file to write and return a server-side file for download.

Casting: String to Boolean

Convert the string value of a number to a Boolean with AS:

Boolean(Number("0"))

Apple Mighty Mouse

It's been a year now that I have been using Apples Mighty Mouse and overall I love it, I must say that it is the best mouse I have ever used, but every once in a while the scroll ball will only scroll in one direction. I've been super aggravated the past few days because I have not been able to scroll up. While this may not seem like a big deal, it is something I have become so accustomed to that I really can't work well without it, in this day and age who can be bothered with scroll bars.

At last, I found the solution and it is so simple I can't believe that I didn't figure it out sooner. If you press hard on the scroll ball and scroll it in all directions it will eventually start working. It only took me about 10 seconds to get mine working again! I'm assuming the ball just gets backed up with dust, etc and it simply needs to be broken loose.

InformIT and Peachpit

As some of you may have noticed many of the article links on Studio Sedition stopped working last night due to the new InformIT and Peachpit web sites. They have all been fixed this morning, sorry for any inconvenience. On the bright side, check out the new design for the sites, it's much cleaner and easier to read the articles.
